Provided you are sticking to the letter and spirity of your rental agreement, you have to set boundaries People that get indignant over you setting boundaries are not worth worried about. 

I believe they are expressing their displeasure with the fact that I have not accommodated some of their recent requests that went far beyond the scope of what is required (like insisting a licensed electrician switch out a smoke detector when we could do it ourselves) and I had to set some boundaries after years of high maintenance for them.

Common fees will include a set-up fee, a leasing fee for each turnover or a lease renewal fee, marking up maintenance, retaining late fees, and more.

This will set up your buy and hold business long term.

I would say get connected with a local agent and also set up with a lender that has you pre approved to make it super easy making offers.

What sets your lisitng apart?

Assuming you already paid for the first occurrence, if it happens again and the plumber doesn't find anything wrong then, yes, the tenant should be responsible for the invoice.Your PM should be setting those expectations when they communicate with your tenant."

Setting up loans as Repo's is something I've thought about a lot, but I wasn't sure if anyone was actually using this.

We try to set up at least 3 timeslots each week when we can schedule all the showings to minimize the tenant interuptions.If they won't cooperate or cancel too many scheduled showings, we warn them we will pursue collections to the fullest extent of the law.
